Patent CA-2180237-A1 (CA)
Inventor: KLOSS HANS GERHARD
IPC: G07F17/32
Filed: 1996-06-28
Abstract: A gaming machine has internal coin container sensors (110, 112) that sense the weight, and therefore, the number of coins contained in the internal coin containers (104, 106). The gaming machine also has mechanical and/or optical sensors (102, 114) to monitor the inflow and outflow of coins. By comparing the number of coins, as determined by weight, with the number of coins detected by the mechanical and/or optical sensors, fraud is readily detected.

Abstract: A symmetric, dispersion-managed fiber optic cable in accordance with the present invention includes a first and a second optical fiber. The first optical fiber is a conventional single mode fiber (SIB) type fiber and has a first effective area and a positive dispersion characteristic at a predetermined operating wavelength range. The first optical fiber is split into two segments each having substantially the same length. The second optical fiber has a second effective area and a negative dispersion characteristic at the operating wavelength range. Typically, second optical fiber is a DSF or an NZD fiber, both with negative dispersion and a small effective area. The second optical fiber is coupled between the two segments of the first fiber to create a fiber optic cable with an average total dispersion at the operating wavelength range which is substantially zero.

Title: Automatic wire twister
Inventor: CROWTHER RICHARD J
IPC: B21F15/04
Filed: 1997-09-24
Abstract: A method and apparatus for automatically twisting two ends of a wire protruding from a stack of rotor lamination parts employs a holder for holding and positioning the parts stack.  A rotatable collar is provided having an aperture through which the two ends of the wire project.  A rotating and reciprocating substantially conically-shaped head traps the wire ends between an inner edge of the rotating collar facing the conically-shaped head and the conically-shaped head when the conically-shaped head is thrust into position against the inner edge of the collar.  A unit is provided for positioning the conically-shaped head against the inner edge of the collar.  A rotating member rotates the conically-shaped head to twist the two ends of wire.  During twisting, clamping jaws clamp a portion of the twisted ends while the conically-shaped head continues to rotate so that a scrap portion of the twisted ends is broken off by wire fatigue and can fall free when the conically-shaped head is moved away from the inner edge of the rotating collar.

Title: Draft hood locating device for combustion apparatus
Inventor: JAMIESON DONALD REGINALD
IPC: F24B1/18
Filed: 1997-10-28
Abstract: A draft hood is provided for mating alignment with a fireplace assembly. The mating alignment is facilitated by the location of alignment hardware fixed to the rear surface of the fireplace and to the inside of the draft hood. In use the hardware permits alignment of the draft hood in a fireplace enclosure without the need to see the fitting, without the need for a long runin slide, and without the need vertically to pivot the draft hood on installation or to pull the flue termination forward of the firebox flue before attachment. For this purpose an updraft detection warning spill tube may also function as one of the alignment fittings since it is, due to its function, located near or at the junction of the draft hood and fireplace.
